ABSTRACT:
The invention relates to a fuel injection device for internal combustion engines and to a method for fuel injection. The invention is directed to an injection nozzle system that while having high intrinsic safety of an injection pump, in the case of electrically controlled pumps, assures fast element filling and simultaneously effective cooling of the injection nozzle as well. According to the invention, an additional final control element is provided between the pump work chamber and the pressure chamber of the injection nozzle and dependent upon the pressure in the pump work chamber the position of the final control element controls a direct fuel delivery path into the pump work chamber.
